[The narration is going to assume at this point that Barry and Iris have traded in their loft for a house, especially when they started having kids.]

The kids are out of town. We could put Mia in Nora's room, and you and your boyfriend in Bart's - that still leaves the guest room and the couch, so yeah. We can make that work.

[And, because speedsters, directly on the heels of those words is a text from Bart: Please don't bang your boyfriend in my bedroom. Not that I expect you to, because you're a polite, reasonable person, but apparently some of Nora's friends need that spelled out for them.]
